Can I redirect the output of tty3 to ttyS0 during install?

Hi,

I am writing an auto-install python script for fedora install test.I do this in KVM, create a guest,when boot to grub,I pass the args(console=ttyS0, console=tty0 ks=http:/server/to/ks.cfg) to kernel via dogtail, by this way, I can get some output from ttyS0 on host(use my script to read from guest serial port on host),but this output information is not enough.During install, I can send key Ctrl+Alt+F3(virt-viewer can send key), the information in /dev/tty3 is what I want to get(I can read this data to auto-control the test),as you know, it also locates in /tmp/anaconda.log, but how I can get this data? can I pass some args to kernel to direct the output of /dev/tty3 to serial port like ttyS0? or what other options I can do? I also tried console=ttyS0 console=tty3,it did not work.I have to do this in non-network environment.

Thanks
Liam
